DESCRIPTION

This disclosure, its aspects and implementations, are not limited to thespecific components or assembly procedures disclosed herein. Manyadditional components and assembly procedures known in the artconsistent with the intended apparatus and/or assembly procedures for astabilizing and power apparatus will become apparent for use withimplementations of stabilizing and power apparatuses from thisdisclosure. Accordingly, for example, although particular handles,bodies, coupling members, biased members, and shoes are disclosed, suchhandles, bodies, coupling members, biased members, and shoes andimplementing components may comprise any shape, size, style, type,model, version, measurement, concentration, material, quantity, and/orthe like as is known in the art for handles, bodies, coupling members,biased members, and shoes and implementing components, consistent withthe intended operation of a stabilizing and power apparatus.

Contemplated as part of this disclosure is an apparatus configured toprovide power and balance or stabilization to a user participating in anathletic and/or movement-based activity. For example, the apparatus maybe utilized by an individual on a skateboard, long board rollerblades,roller skates, skiing, snowboarding, kayaking, ice skating, crosscountry skiing, and the like. Operation and advantages of the apparatuswill become apparent to one of ordinary skill in the art upon review ofthe disclosures presented in this document. Generally, one or moreembodiments of a recreational power and stabilizing apparatus 2 comprisea handle grip 4, an elongated handle body 10 coupled to the handle grip4, a coupling member 20 coupled to the elongated handle body 10, abiased member 25 coupled to the coupling member 10, and a shoe 30coupled to the biased member 25. More specific detail of variousembodiments of a recreational power and stabilizing apparatus 2 shall beprovided herein.

One or more embodiments of a balance or stabilizing and power apparatuscomprise a biased member. The biased member may comprise any biasedmember configured to store and release energy during use. FIGS. 1A and1B depict sides views of a non-limiting embodiment of a recreationalpower and stabilizing apparatus 2 that includes a bowed biased member25, and FIG. 2 depicts a close up view of a bowed and non-linear biasedmember 25 of a non-limiting embodiment of a recreational power andstabilizing apparatus 2. According to some aspects, a biased membercontemplated in this disclosure may comprise any configuration thatallows the biased member to store kinetic energy from the user applyingpressure to the biased member from the handle grip 4 or elongated handlebody 10 as potential energy. For example, a user may apply pressure tothe biased member 25 while in motion (such as a when rolling on a longboard) by pushing the shoe of the apparatus against the ground or othersurface, thus deforming the shape of the biased member 25 and loadingenergy into the biased member 25. As the user continues in motion beyondthe contact point of the shoe 30 of the apparatus 2 and the ground, thebiased member 25 regains its shape and transfers a force or energy tothe user in motion, thus propelling the user.

The biased member 25 may comprise any biased member known in the art,such as but not limited to a non-linear biased member. In thenon-limiting embodiment depicted in FIGS. 1 and 2, the non-linear biasedmember comprises bowed or arced leaf spring biased member 25. As usedherein, a coil spring is a linear biased member and not a non-linear orbowed biased member because when it is compressed axially, its force isexerted axially. According to some aspects, a biased member 25 isnon-linear and extends from a first side 61 of an elongated handle body10, but does not cross a plane collinear with an axis 59 of theelongated handle body 10 more than twice in a total length of thenon-linear biased member 25. As used herein, a curve or arc 60 of abiased member is to be understood to extend beyond the end of the biasedmember itself so that it intersects with a center axis of the elongatedhandle body 10. In one or more embodiments, a bowed or non-linear biasedmember 25 comprises an arc 60 that extends longitudinally relative to anaxis 59 of the elongated handle body, contrary to the coils of a coilspring, which extend latitudinally relative to an axis. It is furthercontemplated that a bowed biased member 25 may comprise an angled,non-linear biased member.

A biased member 25 may comprise any of a number of materials known inthe art, such as but not limited to metals, plastics, and the like. Inone or more embodiments, a non-linear biased member comprises a bowedbiased member 25 comprising fiberglass or carbon fiber (such as a carbonfiber-reinforced polymer). In other embodiments, a non-linear biasedmember may comprise other shapes and configurations utilizing similarmaterials. A biased member 25 may vary in size and dimensions accordingto the desired weight-rated spring loads for different users.

One or more embodiments of a recreational power and stabilizingapparatus 2 comprise a shoe 30 coupled to the recreational power andstabilizing apparatus 2 proximate a second end 42 of a biased member 25.FIGS. 1 and 2 depict a non-limiting embodiment of a shoe 30 on arecreational power and stabilizing apparatus 2, and FIGS. 5A and 5Bdepict close up top and bottom views, respectively, of a non-limitingembodiment of a shoe 30 coupled to a second end 42 of a biased member25. In combination with the biased member 25, a user is able pullhimself (on a skateboard, for example) by reaching the shoe 30 in fronthimself to engage the shoe 30 with the ground. The user then pushes (orloads) the biased element 25 as he/she continues past the shoe 30engaged with the ground until the biased member 25 releases (or springs)and transfers additional force to the user.

In one or more embodiments, a shoe 30 comprises a slot 32, channel,bracket, or the like configured to receive and/or couple to a second end42 of a biased member 25. The slot 32 may be sized such that a portionof the biased member 25 fits between sidewalls of the slot 32. In thenon-limiting embodiment depicted in FIG. 5A, the slot 32 is positionedon a top side of the shoe 30. In other embodiments, a slot may extendinto the shoe 30 or be positioned elsewhere on the shoe 30. One or morecouplings may be used to hold a second end 42 of the biased member 25between the sidewalls of the slot 32, such as but not limited to nutsand bolts 34, screws, pins, and the like and/or any combination thereof.In FIGS. 5A and 5B, the shoe 30 is illustrated as coupled to the biasedmember 25 with a single nut and bolt 34, with a second nut and boltremoved to show the screw opening extending through the biased member25, the shoe 30, and the traction element 35. The one or more couplingsmay extend all the way through to a bottom side of the shoe 30 to alsocouple a traction element 35 to the shoe 30, or may extend onlypartially into the shoe 30. Alternatively, one or more couplings may beused to couple a biased member 25 to a surface of the shoe 30 devoid ofa slot 32. In other embodiments, a shoe 30 may comprise a pin or othermember proximate a terminating end of the slot or a bracket, the pin orother member being configured to support the biased member 25 within theslot or bracket between the sidewalls of the slot bracket, the centerwall of the slot or bracket, and the pin. According to some non-limitingaspects, a shoe 30 is configured to removably couple to a biased member25, thus allowing a user to alternate between different shoeconfigurations depending on the terrain and/or wear on the shoe.

In one or more embodiments, the shoe 30 further comprises a base ortraction element 35. The traction element 35 is configured to providetraction or other engagement between the shoe 30 (or the biased member25) and the surface to which the traction element 35 will interact toprovide energy to the user. According to some aspects, the tractionelement 35 is curved, either with a curve of the bottom of shoe 30 orindependent of the shoe 30. In some embodiments a traction element 35comprises a replaceable brake pad removably coupled to the shoe 30. Moreparticularly, a traction element 35 may be bolted or screwed to the shoe30. In other embodiments, a traction element may be coupled to a shoewith adhesive or other couplings known in the art. In still otherembodiments, a traction element 35 may be coupled directly to a biasedmember 25. A traction element 35 may comprise any durable rubber orrubber-molded piece that is soft enough that it does not slip againsttypical surfaces but strong enough that it is does not easily degrade ortear apart. Although the shoe 30 depicted in the FIG. 5B comprises abrake pad, it is contemplated that other embodiments may comprise awheel, carving element, or other braking element.

In one or more embodiments, a shoe 30 is pivotally coupled to a biasedmember 25. For example, a shoe 30 may be coupled to a biased member 25with a single bolt 34. In such embodiments, the slot 32 may be sized toallow the second end 42 of the biased member 25 to pivot within the slot32. The walls of the slot 32, however, prevent the second end 42 of thebiased member 25 from pivoting beyond a desired angle. Such aconfiguration is advantageous because it allows the shoe 30 to rotate orpivot slightly when the shoe contacts the ground if the elongated handlebody 10 and biased member 25 are at an angle, thus providing anincreased surface area of contact between the shoe 30 and the ground. Inother embodiments, screw holes extending through the shoe 30 maycomprise slotted holes that allow the shoe to pivot upon contact withthe ground.

According to some aspects, a shoe 30 may further comprise a wheel 55coupled thereto. FIG. 6 depicts a non-limiting embodiment of arecreational power and stabilizing apparatus comprising a wheel 55rotatably coupled to the shoe 50. The wheel 55 may be coupled to theshoe 50 with any coupling known in the art, such as but not limited to anut and bolt, pin, screw, rivet, and the like. The wheel 55 may befree-spinning and/or powered by motor 52 housed within or otherwisecoupled to the shoe 50. The motor 52 may powered by rechargeablebatteries or gasoline. According to some aspects, the motor is operablycoupled to an activation switch positioned on the handle or body, suchthat a user may start or stop the motor 52 via the activation switch.

One or more embodiments of a recreational power and stabilizingapparatus 2 further comprise an elongated handle body 10 coupled to thebiased member 25. An elongated handle body 10 is configured to allow auser to direct a biased member 25 and/or shoe 30 during use, as well ashold the recreational power and stabilizing apparatus 2. According tosome aspects, an elongated handle body 10 comprises a shafted elongatedhandle body 10 coupled to a biased member 25. More particularly, theelongated handle body 10 may comprise a substantially straight andcylindrical aluminum shafted body. FIGS. 1A and 1B depict side views ofa non-limiting embodiment of a recreational power and stabilizingapparatus 2 comprising a shafted elongated handle body 10. In otherembodiments, the elongated handle body 10 may comprise other variousshapes, materials, and geometric configurations. For example, the bodymay comprise other materials such as but not limited to plastics, carbonfiber material, wood, metal, and the like.

In some embodiments, an elongated handle body 10 comprises an adjustablelength body, such as but not limited to a shafted telescoping elongatedhandle body 10 comprising a first shaft 6 and at least a second shaft 8.A non-limiting embodiment of an adjustable length body is shown anddescribed in FIGS. 1A, 1B, and 4. In some embodiments, a shaftedtelescoping elongated handle body 10 is adjustable between two or morepositions, such as but not limited to an operating position and acollapsed position. In an operating position, a shafted telescopingelongated handle body 10 extends from a coupling member 20 and is notlikely to interfere with bending or use of the biased member, such asthe non-limiting embodiment shown in FIG. 1A. In a collapsed position, aportion of the shafted telescoping elongated handle body 10 may extendbetween the coupling member 20 and the shoe 30, thus shortening theoverall length of the recreational power and stabilizing apparatus 2 andalso providing and additional handle for carrying the recreational powerand stabilizing apparatus 2 when not in use. FIG. 1B depicts anon-limiting embodiment of a recreational power and stabilizingapparatus 2 in a collapsed position. It is noted that, according to someaspects, a recreational power and stabilizing apparatus 2 is stilloperable in a collapsed position. Various couplings known in the art maybe utilized to lock the elongated handle body 10 in either the operatingor collapsed position, such as but not limited to one or more springpins 15 in the elongated handle body 10 extending through one or moreholes 18 in the coupling member 20. For example, FIG. 3A shows a springpin 15 engaged with a hole 18 on the coupling member 20 locking theelongated handle body 10 in an operating position. A similar engagementbetween other spring pins or couplings on the body may lock the body ina collapsed position.

Whether in an operating position or a collapsed position, a shaftedtelescoping elongated handle body 10 may be adjustable between anextended and retracted position wherein the first shaft 6 slides withinthe second shaft 8, or vice versa, to extend or retract the length ofthe shafted elongated handle body 10. In FIG. 1A, the shafted elongatedhandle body 10 is shown in an extended position, while in FIG. 4 theshafted elongated handle body 10 is shown in a retracted positionwherein the length of the shafted elongated handle body 10 is shorterthan in the extended position. Various couplings known in the art may beutilized to lock the shafted elongated handle body 10 in either theextended or retracted position, such as but not limited to one or morespring pins 15 in the shafted elongated handle body 10 extending throughone or more holes 9 in the coupling member second shaft 8. For example,FIG. 1A shows a spring pin 15 engaged with an upper hole on the secondshaft 8, thus locking the shafted elongated handle body 10 in anextended position. FIG. 4 shows a spring pin 15 engaged with a lowerhole on the second shaft 8, leaving the upper hole 9 open and lockingthe shafted body in a retracted position. Various embodiments maycomprise a plurality of holes for adjusting the length of the shaftedelongated handle body 10 to numerous desired lengths.

Non-limiting embodiments of an elongated handle body 10 may furthercomprise a handle grip 4 coupled to the elongated handle body 10. Thehandle grip 4 may comprise any handle known in the art that provides animproved gripping function for the user. In the non-limiting embodimentdepicted in FIGS. 1 and 4, the handle grip 4 is substantially sphericaland coupled to the elongated handle body 10 opposite the biased member25. Some embodiments, however, may be devoid of such a handle. Otherembodiments may comprise a second handle positioned on the elongatedhandle body 10 between the first handle grip 4 and the coupling member20. Regardless of the shape or configuration, the handle grip 4 may befixed or rotatable to adapt to different grasping positions. In someembodiments, the handle may be grip shaped and have indentations forfinger grips, or be oblong shaped like a typical boat paddle handle.

As referenced above, a recreational power and stabilizing apparatus 2may comprise a coupling member 20 configured to couple an elongatedhandle body 10 to a biased member 25. The coupling member 20 maycomprise one or more of a variety of materials, such as but not limitedto any plastics, carbon fiber material, metals, and the like known inthe art. A coupling member 20 may comprise any coupling memberconfigured to couple an elongated handle body 10 to a biased member 25,and is not limited to the coupling member 20 demonstrated in FIGS. 1-3.According to some aspects, a coupling member 20 comprises a first leg 12configured to couple to an elongated handle body 10 and a second leg 14configured to couple to a biased member 25. The first leg 12 and thesecond leg 14 may comprise any configuration for coupling the elongatedhandle body 10 and the biased member 25, respectively, to the couplingmember 20.

In the non-limiting embodiment depicted in FIGS. 1-3, the first leg 12comprises a body receiver 16 adapted to receive the elongated handlebody 10. More specifically, the body receiver 16 comprises a channelextending entirely through the first leg 12 to allow the elongatedhandle body 10 to slide entirely through the first leg 12. Such aconfiguration allows for adjustable positioning of the elongated handlebody 10 between an operating position and a collapsed position. It isalso contemplated, however, that a body receiver 16 may extend onlypartially into the first leg 12. Accordingly, in various contemplatedembodiments, a body receiver 16 is sized to interface with at least aportion of the elongated handle body 10. A first leg 12 may furthercomprise a hole 18 sized to receive a spring pin 15 to temporarily lockthe elongated handle body 10 in place relative to the coupling member20. In other embodiments, any coupling known in the art may be utilizedto temporarily or permanently lock the elongated handle body 10 in placerelative to the coupling member 20, such as but not limited to screws,bolts, pins, and the like.

A second leg 14 of a coupling member 20 is coupled to a biased member 25in one or more embodiments. FIG. 3B depicts a bottom view of a couplingmember 20 illustrating a non-limiting coupling of a biased member 25 toa second leg 14 of a coupling member 20. In FIG. 3B, a portion of abiased member 25 is positioned within a receiver on the second leg 14,and removably coupled therein with one or more screws 13. It iscontemplated that other embodiments may comprise any other couplingsknown in the art configured to couple a biased member 25 to a couplingmember 20. Due to the bowed configuration of the biased member 25 shownin the non-limiting embodiment of FIGS. 1-3, the second leg 14 is angledfrom the first leg 12.

In other contemplated embodiments, a first end 41 of a biased member 25is coupled to the elongated handle body 10 such that the first end 41 ofthe biased member 25 is offset from an end of the elongated handle body10. In some embodiments, a coupling member is substantially triangularin shape and configured to offset the first end 41 of the biased member25 from the end of the elongated handle body 10. More particularly, acoupling member may comprise a first leg, a second leg shorter than thefirst leg and approximately 90 degrees from the first leg, and a thirdhypotenuse leg extending from the first leg to the second leg. Accordingto some aspects, the coupling member comprises a body receiver orcoupling proximate an intersection of the first leg and the hypotenuseleg. The body receiver may comprise a hole, one or more screws, one ormore pins, one or more nuts and bolts, any combination thereof, or anyother receiver or coupling known in the art and configured to couple thecoupling member to the elongated handle body 10. According to someaspects, the coupling member further comprises a biased member receiverproximate an intersection of the second leg and the hypotenuse leg ofthe coupling member. The biased member receiver may comprise a hole, oneor more screws, one or more pins, one or more nuts and bolts, anycombination thereof, or any other receiver or coupling known in the artand configured to couple the biased member 25 to the coupling member. Insuch a configuration, the first end of the biased member 25 is offsetfrom the elongated handle body 10 of the apparatus.
